Answer:

The sun is a big ball of hot gases and is a nearly perfect spherical ball of hot plasma. About 72% of the Sun's mass consists of hydrogen. The sun is also composed of about 26 percent helium and trace amounts of other elements — oxygen, carbon, neon, nitrogen, magnesium, iron and silicon. The Sun is the star at the center of the Solar System and is by far the largest object in the solar system and the most important source of energy for life on Earth.
